Selection and configuration of air compressor
the "water-lubricated air compressor" of Shanghai Granklin Group can be selected without using oil-water separation filters and oil removal filters, because the "oil-free air compressor" produced by Granklin is 100% oil-free.
General 1. configuration and precautions:
configuration 1: air compressor-gas storage tank-oil-water separation filter-dust removal filter-oil removal filter.
Configuration 2: air compressor-gas storage tank-oil-water separation filter-cold dryer-dust removal filter-oil removal filter.
Configuration 3: Air Compressor-Air Storage Tank-Oil-Water Separation Filter-Cold Dryer-Oil Removal Filter-Adsorption Dryer-Dust Removal Filter.
Each filter has a different role in the system, and generally plays a better role in protecting the rear equipment.
Selection and Configuration of Air Compressor-Picture 1
in the current market, there are also many configurations that are simplified on the basis, but generally speaking, there are some hidden problems in simplifying the configuration. Combined with several cases to illustrate:
1, such as not equipped with oil-water separator; It will cause excessive water content in the air entering the cold dryer, increase the load of the cold dryer, and affect the air quality. A large amount of oil and dust particles entering the cold dryer will cause the drain of the cold dryer to be easily blocked, and the accumulation of oil and impurities on the copper pipe wall of the cold dryer will cause the heat dissipation effect to deteriorate.
2, such as not equipped with gas storage tank; Because the gas storage tank has a buffer flow and cooling effect, and can remove part of the liquid water, in the pressure instability of the pulse flow on the cold dryer impact.
3. If there is no pretreatment, the adsorption dryer is directly connected, such as: air compressor-oil removal filter-adsorption dryer-dust removal filter. This configuration has a very large load on the suction dryer, especially when the intake air temperature is high, the treatment effect will be poor, and it is easy to cause a large amount of water spray from the muffler, which has a great impact on the valve life of the suction dryer.
4. If the temperature of the compressed air entering the cold dryer is too high or the environmental heat dissipation is not good, it is easy to cause the cold dryer to jump or the effect is not good, and the whole machine is unstable.
2. selection of cold and dry machine, should pay attention to the following points:
1. The flow rate, pressure and ambient temperature of the air compressor must be considered in the selection. In general, the flow rate of the air compressor should be consistent or appropriately enlarged compared with that of the dryer, but it should be avoided as small as possible.
2, the exhaust temperature is higher, the need to add a rear cooler, if the user environment temperature is relatively poor, the large unit is preferred to choose a water-cooled dryer. In order to ensure that the intake air temperature is below 45 ℃ and the summer environment is kept below 38 ℃, normal temperature type cold dryer can be selected.
In the configuration of the whole system, generally each cold dryer or each filter should consider the pressure drop of 0.02Mpa. A bypass valve shall be installed at the inlet and outlet of the dryer to facilitate equipment maintenance and overhaul.
There are many types of air compressors, and they are generally subconsciously divided into oil-free screw air compressors and oil-free air compressors. This two in addition to the lubricating oil method is not the same as what is not the same? Mentioned oil-free air compressor many people's first reaction is not oil,
Precision filters are one of the common configurations of air compressor post-processing equipment. What is its function? Why should a filter be configured? For reference only: First of all, because the natural air sucked by the air compressor contains impurities such as moisture and dust, the air
Now it has entered the summer that people love and hate, and the temperature in many places has risen to above 30°C. In the face of the hot summer, screw air compressor temperature is too high by what reason? Summer, screw air compressor is more common fault is scattered
Because the screw oil-free water lubrication air compressor uses water as the lubricating medium to compress air, it provides high-quality 100 oil-free compressed air, no pollution, and the discharged water does not require special treatment, which meets the requirements of environmental protection. In the oil-free compressor market has been recognized by the majority of customer groups
View detailsDifferent brands of low-pressure screw compressors have different prices. Take granklin air compressor as an example. A 7.5kw small oil-based air compressor is about 20,000. This belongs to the middle and high grade, and other brands are either high or low. Of course, there are smaller, 4kw, or piston machines below 7.5kw.
A large amount of data shows that the main cost of the compressed air system is spent on the operation link, and in its life cycle, the operating cost (electricity) accounts for 78-92%. Therefore, how to tap the potential of energy consumption and improve the efficiency of energy use through fine management is the key to every enterprise.
Screw air compressor sometimes work for a long time, resulting in the phenomenon of high temperature, especially in the summer, when the temperature is too high fault often occurs, then the air compressor temperature is too high is how to return a responsibility? 1. Poor environmental ventilation and heat dissipation There are three main situations in which the surrounding environment of the air compressor affects heat dissipation: first, it is too close to wall-like obstacles; Second, there are other heat sources near the air compressor; third, the front door and side doors of the air compressor are open during operation, and the fan cannot form strong airflow.
Air compressor pressure is commonly used in kilograms or Mpa, 16kg is 1.6Mpa, this pressure is commonly used in laser cutting. The traditional piston air compressor can easily reach this pressure, and the oil screw air compressor can also reach this pressure. The water lubricated air compressor Shanghai granklin Group can reach 0.2-4Mpa.
View detailsMedical oil-free air compressor refers to the kind of air compressor suitable for use in medical environmental health conditions. It requires precision, stronger reliability, environmental protection and quiet, fresh and clean compressed air, and the output gas can directly contact the human body. Displacement less than 1m 3/min
A large amount of condensed water will be produced during the working process of the air compressor, which must be discharged in time in order not to affect the normal operation of the unit. There are two main ways of condensate discharge, manual discharge and automatic discharge. Manual discharge has a disadvantage. If the staff forgets to discharge, it will lead
